Are 8x^2y and -5yx^2 like terms? Explain.

MaRussiya [10]3 years ago

Like terms must have the same variables and those variables must have the same powers.

7a^2b^3 and 9a^2b^3 are like terms, because they both have a^2 and they both have b^3.

7a^2b^3 and 7a^3b^2 are NOT like terms, because the powers no longer match.

In your example, do you have the same variables and do the variables have the same powers in both expressions?

Answer:

For example, the years 1600, 2000, and 2400 are century leap years since those numbers are divisible by 400, while 1700, 1800, 1900, 2100, 2200, and 2300 are common years despite being divisible by 4.

Seawater has density 1025 kg/m^3 and flows in a velocity field v = yi + xj, where x, y, and z are measured in meters and the com
olga55 [171]

The rate of flow outward through the hemisphere x² + y² + z² = 9, z >= 0 is zero.

Given that,

Seawater has a density of 1025 kg/m³ and moves at a constant velocity field defined by the equations v = yi + xj, where x, y, and z are measured in meters and the components of V are expressed in meters per second.

We have to find the rate of flow outward through the hemisphere x² + y² + z² = 9, z >= 0.

We know that,

v= yi + xj, and density = 1025 kg/m³

F=1025(yi + xj)

After solving the R(u,v) we get zero.

Therefore, the rate of flow outward through the hemisphere x² + y² + z² = 9, z >= 0 is zero.
